September's numbers stack up about as favorably as any month Des Moines gets. The average high of 78°F sits right at the top edge of the ideal 60–80°F scoring window, and the low of 61°F means even morning rounds stay comfortable rather than stiff. With just 11 precipitation days, it ranks as the third-driest month of the year, and peak wind of 12.2 mph makes it the second-calmest — both conditions that translate directly to more predictable ball flight and fewer weather-forced delays.
What that 17°F daily swing actually means on the course: a 6 AM tee time can feel brisk enough to tighten your swing, while a midday round plays almost like midsummer. The fairways start to firm up as summer moisture fades, adding roll you don't get in July or August. Late-summer moisture carried into September keeps approach shots checking up on most greens rather than releasing toward the back. Taken together, the conditions genuinely favor scoring.
With the second-calmest peak wind of the year and only 11 rain days, weekend morning slots in September book faster than the shoulder-season label suggests — reserve at least a week out for Saturday and Sunday tee times. Midday times midweek often open last-minute as the summer rush fades, making them the best-value window if your schedule is flexible. See how conditions rate hour by hour on our playability scale.
September gives back five degrees off August's 83°F high and drops three precipitation days, so you trade a bit of summer heat for noticeably drier windows — a net gain for most rounds. Moving into October, the average high falls sharply to 63°F, a 15-degree drop that brings real layering requirements and firmer, faster greens, while precipitation days only decrease by one. September's peak wind of 12.2 mph is 1.2 mph higher than August's 11 mph and 1.7 mph lower than October's 13.9 mph — keeping September the calmer bookend of the autumn stretch.
